Stock Screening with High Amplitude, Limit-Order-Book Rankings, and Low K Values
Summary
The post describes a Chinese equity screening rule that combines three conditions: price amplitude above a threshold, appearance on the prior day's market activity ranking list, and a low stochastic-style K value calculated over a rolling lookback. It interprets these as signals of elevated movement, strong short-term attention, and an oversold reading, respectively. Examples show how to combine the conditions into a candidate list.
The proposed idea is to look for volatile stocks attracting market attention while potentially positioned for a rebound. The post warns that volatility increases risk, ranking-list presence does not establish overall strength, and oversold readings do not guarantee a reversal. It suggests adding other technical measures, valuation, capital-flow or sector context, and industry filters. No performance testing or empirical evidence is provided, and the formula description and implementation examples may require alignment around timing and data definitions.
Key ideas
- The screen intersects high price amplitude, prior-day ranking-list appearance, and a low rolling K indicator.
- The author treats these conditions as proxies for volatility, market attention, and an oversold state.
- A low K reading can persist and does not by itself establish that a rebound will occur.
- The post proposes adding technical, valuation, flow, and industry information for broader screening.
